Expected/desired behavior

It should behave and function like Excel. I think with local/static binding there are no issues.

Manually adding an ID to a row in a DataSource bound Spreadsheet is not supported. IDs must only come with the items from the DataSource.

The main scenario, however, is a bug in the Spreadsheet.
